I currently have 640 watts of VHO over a 125 gallon tank. The only complaints I've heard about VHO is that they don't penetrate as well as MH. I do not plan to upgrade to MH, but I was wondering if there would be a benefit to adding 2 more VHO bulbs. Right now I have URI bulbs, 2 super actinic and 2 12,000k daylights.
